Next Moves
Call their next move.
Yes or no: will a billionaire report a stock sale, a buy, or a cut to a fund holding? Every question comes from public SEC filings in our data, and every answer is settled by the next filing. Starting odds come from each person's own filing history. How it works.

No Next Moves market has settled yet. The first ones close at the end of their window.
Past months, checked against filings
The same questions for complete past months, answered from SEC filings. They were never open for trading; they show how a market settles.
How it works
Only public filings. Every question is built from SEC filings already on this site: Form 4 reports of insiders' stock trades (code S is a sale, code P is an open-market buy) and the quarterly 13F reports of the billionaires' funds. Every result links the filing that settled it. Nothing here is about health, family or legal matters.
Starting odds from history. A market starts at the chance our data suggests. For trades we count how many recent weeks had a qualifying Form 4, then turn that into a chance for the whole window. For fund holdings we look at how many top holdings the fund cut last quarter. When the history is too thin, the market starts at 50% and says so. Starting odds stay between 5% and 95%.
How prices move. Buying YES pushes the YES price up; buying NO pushes it down (a standard market-maker formula, the same one the online game uses). A share pays 1 coin if its side wins and nothing if it loses. A void market gives back what you paid.

Play money only. Coins have no value. You can't buy, sell, cash out or send them. Nothing here is investment advice. Game rules.
